I used to use the graduated 1 quart containers generally sold in the
paint section of Home Depot or such. Later I found them at a small resin
distributor for about .23 a piece. Use them a dozen or so times until
they crack or get too scratched up and toss 'em. easier to pour into
than beer cups, wider, and easier to work and stir in, a paint stirrer
